Don't invite Bill O'Brien and Tom Brady to the same St. Patrick's Day party.
The New England quarterback showed a rare display of sideline emotion on Sunday, engaging in a heated argument with his offensive coordinator - one that lasted long enough for head coach Bill Belichick to intervene.
Brady had just thrown an interception in the end zone, late in the Patriots' 34-27 win, giving Washington an opportunity to tie the game on a final drive. When he went to the sideline, he was confronted by O'Brien.
The coordinator seemed to take exception with Brady telling his intended receiver, Tiquan Underwood, to "go and get it." This set off O'Brien, who began screaming at his star quarterback, ripping off his head set to do so.
Brady gave it right back, yelling that Underwood was open and peppering his shouts with profanities.
The two eventually were separated by Belichick.
All of which was just a fascinating side bar. The Patriots (10-3) won at Washington for the first time in franchise history. The Redskins were the only current NFL franchise New England had never beaten on the road.
Brady threw his 294th touchdown pass to move ahead of Warren Moon into sole possession of sixth place for most TD passes in NFL history and reached the 4,000-yard mark for the fourth time in his career.
Two of the TD passes went to Rob Gronkowski, who now has 15 this season. The previous record was 13, held by San Diego's Antonio Gates (2004) and San Francisco's Vernon Davis (2009).
Denver's Brian Dawkins hurt his neck on a play late in the first quarter when he appeared to collide with teammate Robert Ayers as they tackled Chicago's Marion Barber. Dawkins stayed down on the turf for a few minutes before walking off the field on his own.
The former Eagle paced the sideline in a hooded sweat shirt during the second half, giving pointers to rookie safeties Rahim Moore and Quinton Carter, as the Broncos rallied for a 13-10 overtime victory.
Meanwhile, in Glendale, Ariz., Cardinals quarterback Kevin Kolb left the 49ers game after the first series following a blow to the head. The former Eagle was replaced by John Skelton, who directed a 21-19 upset.
New York's Jim Leonhard may be out for the season. Leonhard was hurt when he intercepted a pass by Tyler Palko that was intended for Steve Breaston, and the Kansas City receiver made a twisting tackle. Leonhard was carted to the locker room.
Jets trainers said they would wait until seeing MRI results to make an official determination. Jets cornerback Darrelle Revis mentioned he "did hear something on the sideline that [Leonhard] might be out for the season."
The Jaguars (4-9) scored on offense, defense, and special teams in the same game for the first time since Nov. 1, 1998, at Baltimore.
Drew Brees threw for 347 yards and joined Hall of Famer Johnny Unitas as the only quarterbacks to throw a touchdown pass in 40 straight games. Brees extended his NFL-record streak of games with 20 or more completions to 33.
